Single or Dual Pattern Cam

Some companies do have compression and gear suggestions. I know this isn't your only cam thread. You apparently gave up on the confusion in the last thread. Like Ott said, there is no magic cam for a stock 318. If you are building a car and start fresh with a engine build, you will need the correct convertor and rear gear to match.

Crane always did that. They gave a minimum compression and whether the particular cam "liked" gears and so on. With all of the tricks you can do regarding camshaft timing and ignition curves though, you can widen the "accepted" camshaft choices greatly.
